RADIATOR Filed Aug!. 19, 1927 INVENTR LOUIS.H.VERONNEA Patented Apr. 8, 1930 UNITED STATES LOUIS H. VERONNIA', or MONTIALQ ounnnc, CANADA V RADIATOR Application filed August 19, 1927. Sefial i;o 214,181.

This invention relates to new and useful improvements in radiators and, particulariy, t radiators provided with individual e1ectrie heating elements, and the obj ect of the in- 5 vention is to provide a radiator With means attached thereto for feeding water thereinto in such a manner that the current. consumption of the heating element Will remain practically constant. 7

Another object is to provide a radiator having a feed water tank attached thereto to keep the water within constant level.

In my invention I provide a radiator of the usual type, provided with a heating element connected to a source of electrical cur rent supply. Apertures are formed in the upper portion of the radiator t0 position a feed water tank, the outlet from which is a depending pipe which projects into the radiator. The feedwater tank is provided with a plug fitting into the inlet opening.

The radiator feed water tank outlet is elosed by the water in the radiator and as the water ia1ls below said outlet, the water from the tank tends to keep the water in the radiator at constant leve1.

In the drawings which illustrate one form of my invention V Figure 1 is a perspective view of a radiator with my improved water feed tank attached thereto.

Figure 2 is a sectional side elevation of the radiator shown in Figure 1.

Figure 3 is an enlarged detaii sectional eievation of the heating element..

Referring more particularly to the drawings, 11 designates a radiator having a plurality of horizontal water passages 12, communicating with vertical passages 13 to form a cireulating means for the water within the radiator. The radiator may be provided with stands 14:, to hold the lowermost portion of the radiator c1ear of the fioor and allow the air to pass thereunder. Positioned near the bottom of the radiator is the threaded aperture 15 adapted to receive a heating element designated as a whole by the numeral 16. This heating element may -consist of a threaded p1ug 17 having hol1ow perforated sleeves the radiator at a 18 and 19 projecting irito the radiator. Mounted within the sleeves and spaced from the inner Walls thereof are the carbon or carbon.composite rods 20 and 21 which may be heid in place by means of the rods 22 and 23 insulatedirom the Casing by means of the bushirigs 24- and 25. Therods are connected to a; switch- 2601 the three-way type, which regulates the fiow of current to the heating element. No detail of the switch is shownas any of the standard types well known in this art may be used for this purpose. A common return wire is used and is connected between the switch and thesleeve in any suitabie man ner, such as by means of the terminal stud 27. The switch is connected by means ofthe wire, t0 a source ofcurrent supply (Dot shown) by means of the .plug and socket' connection designated 28. 'A gland 29 may .be bolted or otherwise 'secured to the sleeve andinsuiated therefrom by means of the washer 30 and suitable packing rings 31 may be fitted in the gland and pressed against the insulated cable 32 bymeans ofthe flangedbushing 33', pressure being brought to bear on said bushing38 by means of the nut 34, the thread ed:portion of which engages with the threaded wall of the gland. The glandstrcture is provided to seal theridiator and prevent water from flowing throughfithe aPertures formed'f0r the wiring of the heating ele, ments., It will be noticed that one of the carbon rods is made smalier than the other and this'is provided so that the current consumption of the heating elements may be altered by means of the switch,the smaller heating element being designed to.c0nsume considerabiy 1es s current than the larger. Formedin'the topof the radiator and at each side thereof, are the apertures 35 and 36', eachadapted to receive one of the projections 36 and. 37 ,ofthe feed water tank 38, Which project downwardiytherefrom. Positioned substntialiy midway between said projections is the threadedaperture39 adapted to receive the threaded plug 4:0. .Depending from one of said projections in the feed water tankis the pipe 41, whi'ch forms a source of communication between the interior of the tankand the interiOr of the radiat-or. A

' ably situated on the side of thetank having the projections which fit into the apertures in the radiator. The tank is closedby means of the plug and isthen pIaced'on the top of the radiator Wth the projections fitting into-theapertures inthetop*0f the radiator. The feed pipe frOm the tank is sealed by ma1isofthe water in the fadiator. Curi ent is then supp1ied to the heating element of the larger capacity and when the Water Within the"radiatof hasreached the deSired temperature, thel'arget heating element is cut out and the smaller' element used,aS it is thewater at said desired temperature. The power expended in the circuit is' afiected by the temperature of the Water and theresist ance 1e'ssred so that it rcqiree very little power to keep thc Water near bOiIing Point. There is,of necessity, a certain afioount of evaporation of the water Within the radiator and WhcIr the watear falis below the level of the discharge en'd ofthe tube depending frohthe tank, the Water from the tank fiows into the radiator aHd tends tokeep the water therein at coi1stant'leveh It Will' also be noticed thatthe feed Water from the tank will be ofapproiiiinatelthe same temperature as"-the Wate'r in'the radiator, s'o that the 'feed water Will not affect the current consumption A of the heating elemehts.

The dvice is'vcry simple and inexpensive to manufacture and provides a highly eflicie1it'heating device for moins; fctories' and theiike. It alSo prOVides'a hot water heating* system which is easi1 installed, and which 1S ver economical in 0 eratioh.

Having thus deScribed my invention, what I' daim is 7 A radiator comprising a.casing presenting a top Wall, having a relatiVeiy 1arge opening f0imedthein n'ear each end and a relatively sn'1al'l Ventopming formed therein interndiate Said large Openings, a feed water tank having itsbottom wall directly Supported on the top Wali of said casing, the intermediate portions of the engzzging walls of the casing and tank being' spaced apart to place thevent opening of the; c'asing in communication. with the atmospheie, projectionsdepending fr'0m the bottom Wa1l of said tank andfitting in the relativel large openingS-fned in the my hand.
